Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] Such as figure 1 As shown, a device of the present invention that realizes the COMMAND mode MIPI signal through a bridge chip includes an LVDS to RGB module 1, a COMMAND mode data buffer 2, an image detection module 3, a picture cut command module 4, a COMMAND control module 5, and a COMMAND mode Data processing module 6 and MIPI configuration module unit 7.

[0031] LVDS to RGB module 1 is used to parse the LVDS video signal into RGB video signal, and the analysis includes demodulation clock, pixel clock, line data enable signal, frame data enable signal, and its command and data enable signal. The conversion is completed Then the signal is sent to the image detection module and the COMMAND mode data buffer 2.

[0032] The COMMAND mode data buffer 2 is used to receive RGB video signals and store one frame of image data. COMMAND mode data buffer...

Abstract

The invention discloses a method and device for achieving COMMAND mode MIPI signals through a bridge chip. The device comprises an LVDS-to-RGB module, a COMMAND mode data buffer, an image detection module, an image switching command module, a COMMAND control module and a COMMAND mode data processing module. The device is used for converting LVDS video signals into recognizable COMMAND mode data bus interface signals of the bridge chip to be displayed by a liquid crystal module with an MIPI interface. According to the bridge chip, the RGB video signals can be completely demodulated into the MIPI video signals without errors. VESA / JEIDA LVDS video signals are converted into the RGB signals, and then the RGB signals are converted into the MIPI signals through the bridge chip. The method and device are suitable for the need for the resolution ratio of different liquid crystal modules.

Description

Technical field [0001] The invention belongs to the display field and the testing technical field of liquid crystal modules, and specifically refers to a method and device for realizing a COMMAND mode MIPI signal through a bridge chip. Background technique [0002] MIPI (Mobile Industry Processor Interface) is the abbreviation of Mobile Industry Processor Interface, an open standard for mobile application processors initiated by the MIPI Alliance including ARM, Samsung, Intel and other companies. The bridge chip converts the input signal into MIPI timing interface signal through the internal conversion mechanism in VIDEO mode or COMMAND mode. VIDEO mode refers to the mode that the host transmits to the LCD module using real-time pixel streams, and is a high-speed signal transmission mode, while the COMMAND mode refers to the mode that transmits commands and data to the controller with display buffer. The VIDEO mode is mainly for the operation of the LCD module without frame buff...
